Moisture Removal

August 1, 2011


Air consist of water particles which is usually referred as moisture content of air. So the term moisture removal means removing the unwanted water vapour that is present in a particular volume of air as per requirement. Humidity or moisture level is measured in relative terms and expressed in terms of a percentage. A higher percentage means more water molecules and a humid environment.

Effects of high humidity on Industries/Industial Products

  • Formation of rust and corrosion on steel structures.
  • Peeling or blistering of exterior paint. 
  • Pharmaceutical and Fertilizer  sector suffer from agglomeration of products.
  • FMCG industry faces problem during packaging.
  • Proper blasting and coating of steel structures are not possible.
  • Indoor air quality deteriorates.
  • Environment becomes conducive for mold/mild dew and fungus growth.
  • Damp spots on ceilings or inner surfaces of exterior walls. 
  • POP/Epoxy laying procedures gets elongated as proper drying is not possible when humidity is high.

General Recommendation

Dehumidification is the answer to the above mentioned problems,it is the process through which extra moisture can be removed Through dehumidifcation excess moisture in the air is removed to have moisture free air. Air's moisture content is normally described in terms of relative humidity. Relative humidity(RH) is the amount of moisture it could hold at a particular temperature. 

So when humidity control or moisture removal is referred it actually implies maintaining the RH at the desired level as per the requirements. RH can be controlled by providing dehumidified air or dry air.

Moisture removal is done with the help of dehumidifiers. Dehumidifier draws in the moist air from the surrounding and provides dry and dehumidified air after absorbing the water molecules. So the dehumidifier acts as a dryer.

TDS Solution

Technical Drying Services(TDS) provides dehumidification/humidity control services with the help of desiccant based dehumidifiers.

The desiccant based dehumidifier removes moisture from the air by chemical attraction rather than condensation. Humid air is directed across a desiccant material that acts as a drying agent. The moisture is collected  in the desiccant. The moist desiccant is dried using second hot air stream that heats the desiccant and releases the moisture. Then the desiccant is reused to provide more dry air. In a continuous process the air is dried by the desiccant,at the same time the moist desiccant is dried for reuse so that dry air is available at all times continuously.
